Default Antigravity or NOCO
I need a new battery and I want to try lithium iron. Looking for feedback from members who have used either NOCO or Antigravity.

I have heard great things about the AG battery. I run the lithium from Batteries Plus, going on my 3rd year now.
There was a write up in touring about the Noco, you can do a search, that was not so positive. Noco is the go-to for all the lithium smart chargers, however.

Good luck!

I've got this battery in mine, had it for a little over a year. I haven't had an opportunity to try the restart function yet so I don't know how well it works. I do know my motorcycle starts faster now than it ever has since I bought it new in 2014.

I ran an AG in my chopper for years with zero issues. Once the factory battery dies in my EGS I'll be buying an AG to replace it.

I have been running AG in my Flathead for about 4 years, no issues.

For one of the re-start batteries the information on the website is not use the feature on big v-twin engines. (Don't shoot the messenger!)

The MoCo also used to say that synthetic oil was too slippery to use in their engines.....
Just saying....

Ag was the only battery of the right size healthy enough to spin my big inch shovel over.

The output current is impressive that's for sure. A guy with his Sportster said it was the only battery he found that worked for him.

There are Lithium iron and Lithium Ion, They are not the same.
